Lucas House

Castlecrag NSW

The Lucas House, also known as the ‘Glass House’, with its minimal lightweight construction seems to sit high up in its natural bushland setting like a treehouse.

The house in the Sydney suburb of Castlecrag was designed by husband and wife architects Wilfred Ernest (Bill) Lucas (1924-2001) & Ruth Lucas [née Harvey] (1926-2014) as their own family home following their marriage in March 1956.

Bill Lucas’ ethos that ‘we should be modifying ourselves rather than our environment’ is illustrated in the design of the house. The property falls steeply from the street and the house sits in rugged terrain with a creek running beneath. On a tight budget, the Lucas’ created a building reduced to bare essentials: a timber frame on a simple steel platform supported by four steel columns with steel tension rods. The glass walls provided lightness to construction as does the deck and courtyard void at the centre, though some spaces had been enclosed by the time the house was photographed in 2001.

Bill and Ruth Lucas explained their building intentions in an article published in Architecture in Australia (Oct-Dec 1958): ‘the aims were to leave the site as untouched as possible; to maintain in the building the character of the bush; to provide without frills or fine finishes maximum accommodation and to make up to some extent for the obvious lack of ready-made outdoor living areas.’

The Lucas House is one of five houses and one site of a former house photographed for ‘Fifties houses: plus or minus?’, an exhibition held at Rose Seidler House in 2001. Each of these houses had featured in the 1961 exhibition, 15 Houses by Sydney Architects. The 2001 exhibition asked the questions: ‘Forty years on, what has happened to the… Sydney houses? Have they ‘stood the test of time’, been adapted or conserved, loved or lost?’
